Most reported Ford problems
The rear window wiper may not fully contact the rear window. Our technicians tell us that replacing both the wiper blade and wiper arm will generally correct this issue.
The engine may misfire and/or buck while driving at freeway speeds with no fault code stored in the powertrain control module (PCM). This can be caused by an intermittent fault with the camshaft synchronizer assembly. This condition can be diagnosed by monitoring knock sensor data as per Ford service bulletin #05-22-12. Replacement of the synchronizer assembly will be required to correct this concern.
The Check Engine Light may illuminate, the engine may run rough and have misfires on acceleration. Commonly the ignition coils and/or the ignition coil boots are the cause of this problem. The rubber boot that insulates the coil to the spark plug can dry and crack allowing arcing. Inspect the coils and boots, and replace them as needed. Our technicians also recommend replacing the coil boots any time the spark plugs are replaced.
The common problem for ignition misfires are ignition coils going bad. Replacement of the bad ignition coil is necessary. These should be fixed as soon as a problem is detected. Otherwise the misfire can cause damage to other components.
The magnet for the camshaft position sensor may fall out of its mount and damage the synchronizers. This causes long crank times when starting the engine and may cause the Check Engine Light to illuminate. If this happens, both the magnets and the synchronizers need to be replaced.
The composite (plastic) intake manifold may crack near the thermostat housing and cause a coolant leak. Ford released an updated manifold that was reinforced to prevent a recurrence. No recall was issued for this problem but Ford did extend the warranty to seven years on some models from the date of purchase.
Software enhancements are available to remedy inconsistency and confusion about the Diesel Particulate Filter (DPF) cleaning cycle - “Regeneration” mode. The Powertrain Control Module (PCM) will need to be reprogrammed to add several enhancements, including a more reasonable driving experience during the cleaning cycle and instrument cluster notifications of the cleaning status.
Bad adhesive can cause the foam seal between the dash and windshield to slide out. To correct, the windshield must be removed, and then remove and replace the foam with new parts.
